Valar: https://valar.dev

It's kinda like a private SaaS platform. I just run it for me and a couple of friends right now and just hosting a ton of little fun side projects on it.

e.g. https://tim-efa.valar.app which brings Munich's public transport schedule to your terminal (try it with curl, looks way better)

It supports all kinds of things like bring-your-own-domain, e.g. I run my portfolio page https://espe.tech on top of it. It is partly open-source (actually only the CLI for now) but I plan to fully open-source it in the future after cleaning up the code a bit and improving testing and stuff :)

New comment by lnsp in "Cloudflare Calls"

lnsp — Tue, 27 Sep 2022 13:48:50 +0000

As far as I understood it: the premise of added security is based on the fact that the other WebRTC peers only see Cloudflare's IP instead of your own. Also nobody knows who you are exactly talking to except Cloudflare. I would still expect that the media channels itself still remain encrypted when even when multiplexed by Cloudflare's network.

edit, yes it's encrypted:

> Finally, all video and audio traffic that passes through Cloudflare Calls is encrypted by default. Calls leverages existing Cloudflare products including Argo to route the video and audio content in a secure and efficient manner.

lnsp — Sun, 19 Jun 2022 20:16:26 +0000

Cloudflare provides an immense value for small sites. Doing DDoS protection with specialized firewall hardware was one of the most expensive things you could do, so it wasn't really affordable for lots of people. They win by solving a problem. I believe that the issue of Cloudflare as a man-in-the-middle is a smaller issue for people running websites than the damage done by potential attacks.

Great to see new features being implemented. I'm using DuckDB for a thesis project and integrating it into my own Python CLI/web tool has been super easy -- I especially love the direct integration with DataFrames, it makes things really seamless.

New comment by lnsp in "Ask HN: How many computers you got?"

lnsp — Tue, 10 May 2022 13:17:40 +0000

I got a

- main desktop PC (AMD Ryzen 5950X, 64GB, 2TB SSD) I use for basically everything when I'm doing stuff at home (dual boot Linux/Windows)

- a recent 2021 14" MacBook Pro (which replaced an older 2016 MBP) for university

- a 4th-gen iPad Air with Pencil (mostly note-taking and occasional media consumption)

- my previous desktop PC (Intel 3770k, ~12TB storage) stuffed full of storage, just a place where I can throw data I don't immediately need anymore

- a Raspberry Pi 4 with a 512GB SSD attached, running some home services like DNS

So 5 in total not counting my phone.

lnsp — Mon, 09 May 2022 21:31:06 +0000

> Litestream has a new home at Fly.io, but it is and always will be an open-source project. My plan for the next several years is to keep making it more useful, no matter where your application runs, and see just how far we can take the SQLite model of how databases can work.

As far as I understood it, Fly.io hired the person working on Litestream and pays them to keep working on Litestream.

New comment by lnsp in "Cloudflare R2 Pricing"

lnsp — Thu, 05 May 2022 14:56:40 +0000

I guess in the long term the product will at least pay for itself, in the short term it will just be a marketing campaign and gives people a good reason to switch from their Amazon stack in case they don't depend on things like EC2-S3 transfers. When comparing to Backblaze B2 [1], Cloudflare's storage cost is 3x but you don't pay for egress as a tradeoff (compared to 0.01$/GB for Backblaze).

lnsp — Tue, 22 Mar 2022 13:18:54 +0000

Isn't this solved by a large scale find-and-replace for existing scripts? Sure, the changes can be inconvenient but it's not like a major API change or something. They've also been printing out warning messages since December 29th according to the issue, so I'd expect that people would have updated their pipelines by now.

TLDR: Your Let's Encrypt certificate may have an RSA private key. Go's TLS implementation is far better optimized for ECDSA keys. Switching from RSA to ECDSA saves about 95% of CPU cycles due to the better implementation.

According to GH Status (https://www.githubstatus.com/), everything is fine. Gotta love functional status pages.

edit: Nevermind, they just reported "degraded performance" for GitHub Actions, Issues, and Pull Requests.
